Assessment of the Respiratory System in
Workers Occupationally Exposed to Phosphorite and Apatite Dusts
Mikulski T, Podraza H, Steciuk W, Swiech
Z
In a study of the effects of phosphorite and apatite (1306-05-4)
dusts on respiratory function, industrial hygiene monitoring of
workplace total and respirable dusts was performed on a cohort
of 118 males, mean age 37.3 years, who had been employed in processing
phosphorite and apatite ores for a mean of 8.6 years. The comparisons
consisted of 149 healthy males, mean age 35.6 years, who had never
been exposed to phosphorite or apatite dusts. Approximately 67%
of the subjects in each group were smokers. The subjects completed
a respiratory symptom questionnaire, pulmonary function testing
was performed, and chest X-rays were obtained. Total workplace
dust concentrations ranged from 14 to 228 milligrams per cubic
meter. The respirable fraction accounted for approximately 18%
of the total dust concentrations and consisted primarily of calcium-oxide
(1305788), phosphorus oxides, silica (14808607), and fluorides.
Both the cohort and comparisons reported similar prevalences of
chronic cough, excess sputum production, and dyspnea, 15 and 12%,
respectively. The chest X-ray films of both groups were similar.
Group mean values of forced vital capacity (FVC), 1 second forced
expiratory volume (FEV1), and maximum expiratory flow at 25% (MEF25)
and 75% of FVC (MEF75) were significantly lower in nonsmoking
phosphorite and apatite workers than in nonsmoking comparisons.
Mean transit times (MTTs) were significantly longer in the nonsmoking
exposed workers than in nonsmoking comparisons. These changes
were not significantly associated with duration of phosphorite
or apatite exposure. FVC, FEV1, MEF25, maximum expiratory flow
at 50% FVC, MEF75, and MTT were significantly decreased in smoking
comparisons relative to smokers in the cohort. No smoking related
changes in these parameters were seen in the exposed workers.
The authors conclude that occupational exposure
to phosphorite and apatite dusts causes decrements in pulmonary
function in nonsmoking workers.

Nonasbestos Pulmonary
Mineral Fibers in the General Population
Churg A
The pulmonary nonasbestos mineral fiber content was analyzed in
the lungs of 20 individuals who had no occupational exposure to
fibers. Thirteen different mineral species were identified which
accounted for 71 percent of the fibers counted. Among those found
were apatite (1306-05-4), talc (14807966),
attapulgite (1337764), gypsum (13397245), silica (7631869), rutile
(13463677), kaolinite (1318747), mullite (1302767), illite (12173603),
pyroxene (12174377), pyrophyllite (68136618), feldspar, vermiculite
(1318009), and chlorite (1318598). The average number of nonasbestos
fibers for the 20 cases was 106,000/gram wet lung. There was no
significant difference recorded between smokers and nonsmokers
nor was there a difference based on age. Apatite
was the most frequently observed fiber with a mean of 19,000 fibers/gram
wet lung, or 18 percent of the nonasbestos fibers present.
Talc was the next highest in concentration and together talc and
apatite constituted over one third of the total fibers present.
Only silica was found in every lung sample. Eighty six percent
of the fibers were between 1 and 4.9 microns in length with 3
percent being over 10 microns in length. Concerning distribution
in the lungs, the mean number of fibers in the subpleural upper
lobe was 30,500; in the peripheral lower lobe 37,000; in the central
upper lobe 19,500; and in the central lower lobe 19,500 fibers/gram
wet lung. Interstitial fibrosis did not occur in any patient unless
it was explainable as a result of treatment or old infectious
disease. Three of these individuals had lung cancer and one had
gastrointestinal cancer but in none of these individuals were
there any differences in nonasbestos fiber content in the lungs
when compared to other members of the study group.

Prevalence of Pneumoconioses
among Phosphate Rock Workers in Brazil
de Capitani EM
The prevalence of pneumoconioses among phosphate
(1306-05-4) rock workers in Brazil was assessed. The 73
workers evaluated in the investigation were exposed to phosphate
rock extracted in the states of Goias and Minas Gerais, where
the material was crushed and then transported to Paulinia for
storage in underground mills. Subjects submitted to a detailed
respiratory questionnaire, a physical examination emphasizing
the respiratory system, pulmonary function tests, chest x-rays,
and, in two cases, lung biopsies through thoracotomy. The quantity
of free silica (7631869) in airborne samples was measured by colorimetric
analysis. A semiquantitative analysis was performed on airborne
samples using x-ray spectrometry. Twenty
of the workers were noted to have pneumoconioses. Mean exposure
was 46 months. The majority of the cases had no respiratory
symptoms. No significant fibrosis was noted, and no pleura disease
or mediastinal alterations were observed. No traces of free silica
were detected by diffraction analysis. The author concludes that
the high prevalence of pneumoconioses noted in this study must
derive from the particularly poor working conditions at the facilities.
A regular followup using lung function tests and chest x-rays
should be included in the routine examination of phosphate rock
workers.

In order to evaluate the magnitude and effect of phosphate
(fluorapatite) rock particles on the distribution of fluoride
in the Jordanian sector of the Gulf of Aqaba, sea water and sediment
samples were collected from six stations north and south of Aqaba
Port. The fluoride concentrations of the water and sediments were
determined, together with the concentrations of calcium, calcium
carbonate, total phosphorus, magnesium and organic matter in the
sediments. Normal fluoride
concentrations were found in the sea water samples, whereas
abnormally high values were found
in the phosphate-polluted sediments. These findings and
the correlations between fluoride concentrations and those of
other measured parameters are discussed.

Assessment of the Nasal Mucosa in Workers
Exposed to the Prolonged Effect of Phosphorite and Apatite Dusts
Mickiewicz L, Mikulski T. Kuzna-Grygiel
W, Swiech Z
The nasal mucosae of workers subjected to prolonged exposure to
phosphorite (PH) and apatite (1306-05-4)
(AP) dusts were examined.
A group of 131 male workers employed at the harbor quay in the
transshipment, transport, and storage of PH and AP ores was selected.
They had been occupationally exposed for an average of 8.6+/-4.7yr,
working about 6 hours per day. The control group of 129 workers
were employed in the transshipment of general dustless cargo.
Laryngological and cytological examinations of nasal mucosa smears,
as well as urinary examination for fluorine (F) ions were conducted.
Results showed that urinary F ions in the
exposed group increased from 0.8 milligrams per liter (mg/l) before
work to 1mg/l after work, and was higher than that in the control
group (0.63mg/l). Rhinoscopy showed that inflammatory changes
corresponding to chronic, simple, or atrophic
rhinitis were more frequent in the exposed group. The
number of atrophic rhinitis•
cases increased with years in the
workplace, and in those who had worked longer than 10yr, incidence
was about 53%. Cytologically, exposed
workers displayed stratified squamous epithelium or metaplastic
cells, together with degenerative, inflammatory changes. The number
of morphotic elements of epithelial and nonepithelial origin was
greater than in the control group. The authors conclude
that cytological screening can be used for assessing the effects
of PH and AP dusts on the nasal mucosa.

• Definition: Atrophic rhinitis
Atrophic rhinitis is characterised by squamous metaplasia followed
by atrophy. The nose becomes filled with foul smelling crusts.
The smell from these crusts may cause the child to be ostracized...
The cause of atrophic rhinitis is unknown, although bacterial
infection frequently plays a role. The mucous membrane changes
from ciliated pseudostratified columnar epithelium to stratified
squamous epithelium, and the lamina propria is reduced in amount
and vascularity. Anosmia results, and epistaxis may be recurrent
and severe. Atrophic rhinitis is differentiated from other forms
of chronic rhinitis by the abnormal patency of the nasal cavities,
caused by atrophy of the blood vessels and the seromucinous
glands in the lamina propria.

(Investigation on the effects of a singly

dust to rat lungs.)
HOLLENBACH K, KERSTEN E, PATZELT K, SCHWESINGER
G
Fifty mg of apatite-concentrate and apatite-nepheline (apatite
ore), suspended in 1 ml of physiological saline solution, were
applied once intratracheally to female albino rats. Twenty-six,
39 and 52 wk later the animals were sacrificed and a histological
examination of the macroscopically affected parts of the lungs
and the paratracheal lymph nodes was done.
In all 52 wk animals a histocytical and fibrocytical formation
of nodules in the lungs with a desquamation of the epithelia and
metaplastic modifications of the plateepithelium of the bronchial
mucous membrane was observed. Application of apatite-concentrate
resulted in a lympho-plasmacellular reaction with subsequent leucocytical
infiltration. In both dust samples the examined lymph nodules
showed the symptoms of a chronic lymphadenitis. Apatite-ore
causes a fibrous injury of the parenchyma of the lungs. This damage
was not observed in the case of apatite-concentrate.

Small-airway lesions in patients exposed
to nonasbestos mineral dusts.
CHURG A, WRIGHT JL
Dep. of Pathol., Univ. of British Columbia, 2211 Wesbrook Mall,
Vancouver, BC V6T 1W5, Canada.
Small-airway lesions were identified in histologic sections from
the lungs of 7 workers with histories of exposure to nonasbestos
dusts. The lesions consisted of deposits of fibrous tissue, often
accompanied by pigment, in the walls of membranous and respiratory
bronchioles and alveolar ducts. Comparison
with a matched population of persons with no dust exposure revealed
that the changes in the respiratory bronchioles and alveolar ducts
were morphologically distinctive and could be used to diagnose
the lesions. Structurally, these lesions were similar to
those described in the airways of asbestos workers, although comparison
with the authors' previous results indicated that the number of
severely affected airways was less in the nonasbestos dust group.
Mineralogic analysis indicated that these abnormalities were produced
by a variety of different dusts including silica, iron oxide and
aluminum oxide, and that occult asbestos exposure, although possible
in 3 cases, was most likely not a primary cause of disease. This
lesion, called mineral dust airways disease, was a nonspecific
reaction of the small airways to inorganic particulates.
The presence of such changes cast doubt on the theory that small-airway
abnormalities in asbestos workers were the earliest form of asbestosis.

Fluids were withdrawn 6 h after injection and examined for leukocyte
counts, protease, prostaglandin E2 (PGE2) and tumor necrosis factor
(TNF) levels. CPPD crystals (especially
monoclinic CPPD) induced higher numbers of leukocytes,
and more protease, PGE2 and TNF than apatite. CPPD seemed to play
a predominant role in the acute inflammation induced by mixed

The aim of the study was to determine if solid, slightly soluble
compounds can be used as nutrient source in activated sludge treatment
plants instead of liquid phosphoric acid. Four different solid
materials were tested in lab-scale solubility tests to find compounds
which are least soluble. Two materials were chosen for further
studies: apatite and raw phosphate. The use of apatite and raw
phosphate as nutrient source was studied in lab-scale activated
sludge reactors along with a control reactor where phosphorus
was added in liquid form. The phosphorus dosage, measured as elementary
phosphorus, was the same for all three reactors. The reactors
were fed with pre-clarified chemi-thermomechanical pulp mill (CTMP)
wastewater. There were no significant differences in the reductions
of organic matter between the three reactors. The mew effluent
concentration of total phosphorus was 3 mg PA in the control reactor
and less than 1 mg P/l in the other two reactors. The soluble

Several naturally occurring Ca-phosphate apatites which varied
in crystalline structure and ionic composition were added as crystals
of different particle size to P-free (< 1 mug/l total P) nutrient
media. Sufficient %W%000006%% was released by the partial dissolution
of apatite crystals at limnetic pH levels (pH 7.8) to support
growth of several unialgal-mixed bacterial culture. The biomass
produced by mixed populations increased as the amount of available
apatite was increased and as the pH of the media and the particle
size of the apatite crystals were decreased. Although apatite
characteristically displays reduced solubility under alkaline
conditions, the tons of apatite which are
continuously entering aquatic environments as erosion material
may be contributing to the P loading of those ecosystems. (The

Phosphorus cycling and phosphorus sources
in Lake Kinneret: Tracing by oxygen isotopes in phosphate.

The isotopic composition of oxygen in phosphate (delta18Op) in
sediments and suspended matter of Lake Kinneret (L.K.) serves
as a tracer of phosphorus sources and sinks. delta18Op and the
distribution of phosphate concentrations in different fractions
of the sediments were measured at a number of stations in the
lake and in its catchment basin. Sequential extracts of phosphate
show that the major fraction of phosphorus in L.K. sediments is
linked to calcium, either as apatite or as a surface complex on
calcite crystals. A minor fraction is adsorbed on clays and iron
hydroxides. No iron-phosphate or aluminum-phosphate minerals were
detected. Approximately 70% of the particulate
inorganic phosphate entering L.K. is
from a basaltic source (delta18Op = 6). This
includes the detrital sand fraction (probably fluorapatite) most
of which sinks to the bottom immediately upon entering the lake
and is thus mechanically removed from the cycle. Only 40%
of the phosphate in the silt [abstract truncated]

The article provides data on the study of occupational and non-occupational
factors relating to the prevalence of early spontaneous abortions
in couples engaged in fertilizer production. A higher degree prevalence
of early spontaneous abortions was detected in several groups
affected by specific factors. As this degree of prevalence was
found in the groups in which it was only the father that had been
exposed to the specific hazardous factors, it was considered that
the factors in question eithe capable of their own germ cell mutagen
action. It was established that lowered mutagen tolerance related
to early abortions was markedly higher in groups exposed to organic
substances' compounds and industrial noise.
