Toxicology and hazard assessment of 1,3-Dichloropropene (Telone II)
Potential adverse health effects from occupational exposure to 1,3-dichloropropene (DCP) are reviewed and hazards assessed. Further toxicologic evaluations should be conducted using only high-purity material that is free from possibly confounding impurities and stabilisers. Safety considerations when handling the material are included.

Occupational exposure to 1,3-dichloropropene (Telone II) in Hawaiian pineapple culture
1,3-dichloropropene (DCP), the primary constituent of Telone II, is a subsoil fumigant that has supplanted 1,2-dibromo-3-chloropropane (DBCP) and ethylene dibromide (EDB) as primary fumigant in Hawaiian pineapple culture. To determine the potential for adverse health effects, an environmental survey was done to assess worker exposures. Exposures were predominantly below 1ppm, which is the no-effect level determined with experimental animals, and the Threshold Limit Value (TLV) recommended by the American Conference of Governmental Industrial Hygienists (ACGIH).

Outbreak of Omite-CR-induced dermatitis among orange pickers in Tulare County, California
An outbreak of dermatitis cases among 198 orange pickers employed by a Tulare County, California, packinghouse was investigated. Dermatitis was contracted by 114 (58%) of the 198 workers exposed when Omite-CR-treated fields were harvested. The dermatitis occurred predominantly in the exposed areas of the neck and chest. A dose-response association with dermatitis was suggested for Omite-CR (Propargite) exposure, but not for Carzol, Omite-CR + Carzol, or other pesticides. Because no violations of pesticide preharvest intervals or application rates were found, it appears that residue degradation was not given adequate consideration in the registration of Omite-CR, thus compromising the safety of the worker.

Irritation and sensitization potential of pesticides
A pesticide series of 36 substances was patch tested in 652 subjects to establish the optimal test concentration and the frequency of irritant and allergic reactions. Allergic reactions to fungicides were found in 46 thiophthalimides (captan, folpet and difolatan) were the most common. Irritant and allergic reactions to other pesticides (insecticides, herbicides, etc.) were rare. Sensitivity to pesticides was significant in patients who work, or have worked, on the land. Cross sensitivity to bis-dithiocarbamates or thiophthalimides is possible.

Assessment of potential acute health effects in agricultural workers exposed during the application of chlordimeform
Agricultural workers exposed to chlordimeform (Cdf) used as a pesticide on cotton were monitored. Cdf metabolites were found in the urine of 132 workers and were positively correlated with the length of exposure and nature of job activity. Persons mixing and loading and engaged in miscellaneous tasks such as cleaning and maintenance of equipment had the greatest exposure. There was no evidence of urinary tract irritation by microscopic analysis of the urine, nor were significant differences found between preseason and postseason serum chemistry results. Despite the use of protective clothing and closed system transfer devices, Cdf was absorbed by workers as evidenced by urinary metabolite excretion.

Semen quality in papaya workers with long-term exposure to ethylene dibromide
A cross-sectional study of semen quality was conducted among 46 men employed in the papaya fumigation industry in Hawaii, with an average duration of exposure to ethylene dibromide (EDB) of 5yrs and a geometric mean breathing zone exposure to airborne EDB of 88ppb (8h TWA) and peak exposures of up to 262ppb. The control group consisted of 43 unexposed men from a nearby sugar refinery. Significant decreases in sperm count per ejaculate, the percentage of viable and motile sperm, and increases in the proportion of sperm with specific morphological abnormalities (tapered heads, absent heads, and abnormal tails) were observed among exposed men by comparison with controls after consideration of smoking, caffeine and alcohol consumption, age, abstinence, history of urogenital disorders, and other potentially confounding variables. No effect of exposure to EDB on sperm velocity, the overall proportion of sperm with normal morphology, or YFF bodies was observed. These data strongly suggest that EDB may increase the risk of reproductive impairment in workers at exposure levels near the NIOSH recommended limit of 45ppb (as an 8h TWA) and far below the current standard of the Occupational Safety and Health Administration of 20ppm.

Respiratory exposure of grain inspection workers to carbon tetrachloride fumigant
The point at which peak exposure occurs during the grain inspection process has been identified as the off odor test in which the inspector smells the grain sample for rancidity, sourness, etc. Ambient concentrations of CCl4 in 7750 grain samples submitted for inspection were determined by colorimetric tube, and these concentrations were an estimate of peak grain inspector exposure to CCl4. The average ambient concentration of CCl4 per grain sample was 1.69ppm ±8.35. Approximately 380 time-weighted average (TWA) CCl4 exposures for grain inspection workers were determined by using passive dosimeters. All TWA exposures were less than 2ppm. Variables are examined, such as location of work, grain type, time of year and grain transportation vehicle - all of which are known to the sampler or inspector before performing their job functions and which affect potential exposure.

Insecticide use and increased mortality in rural Central Luzon, Philippines
This mortality study covered the inhabitants of 4 municipalities in a major rice-growing area of the island of Luzon (Philippines). Two periods were compared, one of low pesticide use (1961-1971), and one of high use (1972-1984). The non-traumatic mortality rate for adult men increased between the 2 periods by 27%, while that of women and children decreased significantly. It is suggested that the significant mortality increase in men is entirely due to exposure to insecticides among farmers, who wear normally no protective clothing during the spraying of insecticides such as carbofuran, endrin, parathion and monocrotophos (= azodrin).

Bases for a MAC for vinyl phosphate in workplace air
Materialy k obosnovaniju PDK vinilfosfata v vozduhe rabočej zony [in Russian]
Vinyl phosphate (VP) (insecticide) toxicity was tested on mice, rats and guinea pigs in acute and chronic experiments in order to determine an occupational exposure limit. The compound displayed low toxicity when administered orally, by inhalation or percutaneously. Lim(ac), Lim(ch) and Lim(sp) upon inhalation exposure were 94.88, 10.54 and 31.6mg/m3, respectively. LD50 for different species studied ranged from 1170.8 to 2480mg/kg. No sensitising effects were observed. The VP preparation's cumulative effects subsided with the lowering of the daily dose. A MAC of 1mg/m3 (vapour + aerosol) was proposed and approved (hazard class III).

Worker exposure to a herbicide applied with ground sprayers in the United Kingdom
This study was designed to measure potential dermal and respiratory exposure during the application of 2,4-dichlorophenoxy acetic acid, with 5 types of application equipment commonly used in the United Kingdom. Potential dermal exposure was higher during mixing and loading all tractor-powered sprayers than during spraying. Potential dermal exposure from tractor-powered sprayers fitted with conventional hydraulic nozzles was lower than from knapsack sprayers, with exposure from a tractor-powered sprayer fitted with controlled-droplet application equipment intermediate in this regard. There was no difference in potential dermal exposure between tractor-mounted and tractor-drawn sprayers fitted with conventional hydraulic nozzles. The hands were the most highly exposed part of the body during mixing and loading operations for all sprayers, and during spraying with tractor-powered sprayers. The lower legs of the workers were exposed principally when knapsack sprayers were used. For all 5 sprayers, potential respiratory exposure, where detectable at all, was negligible compared with potential dermal exposure.

Gloves for protection against toxic substances. Methods for determining permeability, cleanability and stability [USSR]
Sredstva individual'noj zaščity ruk ot toksičnyh veščestv. Metody opredelenija pronicaemosti, očiščaemosti i stojkosti [in Russian]
This standard (effective 1 Jan. 1988) applies to gloves of natural and synthetic rubber, gums and polyvinyl chloride, with or without textile reinforcement, and gives methods for determining their permeability, cleanability and stability with respect to liquid pesticides with maximum saturated vapour concentrations greater than 10mg/m3 at 25°C. Permeability is determined by exposing one side of a sample of glove material to pesticide and measuring the amount of pesticide absorbed by a piece of filter paper in contact with the opposite side of the sample. Cleanability is determined by measuring the amount of pesticide adhering to a sample of material before and after washing with an alkaline soap solution. Resistance to pesticides is determined by measuring the puncture strength (unreinforced material) or ultrasound attenuation (reinforced material) of a sample before and after exposure to pesticide.

Effect of organophosphoric pesticides on the behaviour of NBT-dye reduction and E rosette formation tests in human blood
These investigations revealed a significant decrease in the values of the examined cellular parameters of human immunity and in the absolute lymphocyte count in peripheral blood in 31 workers, as compared to 30 controls. Moreover, the NBT-dye reduction decrease was correlated with a reduced acetylcholinesterase (AChE) activity. The exposure time showed a negative linear correlation with the phagocytic index of the NBT-dye reduction test. It is concluded that depressed NBT-dye reduction and diminished spontaneous E rosette formation may be regarded as a reflection of the effect of organophosphoric chemicals on metabolic and membrane damage of human cells. A possible role of endogenous acetylcholine poisoning in the development of these pathologic conditions is also discussed.

Biological indicators for the assessment of human exposure to industrial chemicals: Alkyl lead compounds, dimethylformamide, mercury, organophosphorus pesticides
The available data on the human health effects, metabolism and biological indicators of these substances are reviewed. Conclusions reached: determination of the substance (or its metabolites) in urine may be used for assessment of occupational exposure to organic lead, dimethylformamide, mercury vapours and inorganic mercury compounds; the measurement of mercury in blood may be used for evaluating exposure to organic mercury compounds; for organophosphorus pesticides, urinary excretion of metabolites is the best indicator of internal dose, while measurement of blood cholinesterase is the most important indicator of exposure.

Exposure to dust and mancozeb during the transplanting of pine seedlings
Exponering för damm och mancozeb vid upptagning av tallplantor [in Swedish]
Report on exposure to dust and Mancozeb during the manual transplanting of pine seedlings at a Swedish tree-nursery. These seedlings are treated with the fungicide Mancozeb (which contains manganese) during the growing period (1-2 years). In this study the total dust was measured and analysed with regard to manganese content. The results showed that exposure to Mancozeb was very low, less than 0.02mg/m3. No significant difference was found between samples from a surface treated with Mancozeb and another untreated one. The mean exposure to total dust was 2.2mg/m3 (time weighted average for a whole working day).

Hygienic characteristics of the working conditions in agricultural aviation and state of health of maintenance personnel
Gigieničeskaja harakteristika uslovij truda i funkcional'nogo sostojanija tehnikov sel'skohozjajstvennoj aviacii [in Russian]
Agricultural aviation maintenance personnel, unlike transport aviation maintenance workers, are exposed to pesticides which produce hepatotoxic effects. They have high incidences of diseases of the respiratory system, musculoskeletal system and connective tissue, and of radiculitis during their first 5 years of work, resulting in temporary disability. To improve working conditions, loading of pesticides should take place at loading points provided with special machines to prevent contamination of the workplace air and of workers' skin. All repair work and equipment regulation should be conducted with obligatory use of personal protective equipment. It is necessary to determine total and direct bilirubin and β-lipoproteins, activity of alkaline phosphatase alanine aminotransferase and histidase for timely detection of liver function disorders.

Characteristics of the toxic action of cyclofos under conditions of continuous and intermittent exposure
Osobennosti toksičeskogo dejstvija ciklofosa v uslovijah monotonnogo i intermittirujuščego vozdejstvija [in Russian]
Continuous intratracheal administration of cyclofos caused a more pronounced toxic effect than intermittent administration did. Inhibition of the monooxygenase enzyme system of the liver and lungs was observed on continuous exposure, and induction of this system with more evident changes in lungs on intermittent exposure. The results were used as a basis for a MAC for cyclofos in workplace air for agriculture of 0.5mg/m3 (vapour + aerosol), with indication "penetrates through skin; hazard class 2".

Experimental basis of a MAC for ricid-II in workplace air for its agricultural application
Ėksperimental'noe obosnovanie predel'no dopustimoj koncentracii ricida-II v vozduhe rabočej zony dlja uslovij ego sel'skohozjajstvennogo primenenija [in Russian]
Experimental studies on animals with the organic thiophosphate ricid-II (Kitazin P) revealed no marked embryotoxic effect and no adverse effects on progeny. A single ricid-II inhalation showed no mutagenic action in rats. It showed allergenic properties on intracutaneous injection. The recommended MAC for ricid II in workplace air is 0,5mg/m3 (hazard class 2 with indication "allergen").

Hygienic assessment of the cardiotoxic action of some pesticides
Gigieničeskaja ocenka kardiotoksičeskogo dejstvija nekotoryh pesticidov [in Russian]
The cardiovascular system in rats (mature animals and embryos) exposed to pesticides (acetochlor, dianat, isophos-3, sumilex) was studied. A complex of cytomorphological, histochemical, biochemical and electrophysiological methods was used in the study. All the above-mentioned chemicals administered in high doses produced stereotypic heterogeneous disorders of cell structure and function, as well as vascular and microcirculatory disturbances. Lesions in the elements of the cardiovascular system depend on concentration and duration of exposure: effects were more evident in rats exposed to dianat and acetochlor, less evident in those exposed to isophos-3 and sumilex. Administration of low doses of pesticides revealed some features of their biological action on the elements of the cardiovascular system that dependend on the chemical structure of the individual compounds. Cardio-bioelectric activity in rats at different stages of ontogenesis was studied. The pesticides showed an ability to cross the placenta and affect the foetus.

A test series for pesticide dermatitis
A pesticide patch test series was tested in 200 subjects, 50 of whom were agricultural workers. Positive reactions to fungicides were found in 24, almost all to thiophthalimides, especially captan, difolatan and folpet. Reactions to bis-dithiocarbamates and benomyl were rare, and to other pesticides not significant.
