The problem of environmental pollution is of everybody's concern. Pollution of Zarjoub river in northern Iran is most often cause by the uncontrolled disposal of sewage and other wastes resulting from domestic uses of water, industrial wastes containing a variety of pollutants, agricultural affluent from animal husbandry, drainage of irrigation water and urban run-off. A study was carried out to determine the concentration of industrial wastes irrigation water Nitrogen and Phosphorous in six station of Zarjoub River. The analysis was performed according to American Standard Method. The results of three months water analysis showed that the concentration of Nitrogen and Phosphorous which annually discharged into the Pahlavi Lagoon were 931 and 184 tons respectively. For a better analysis a programmed monitoring is required in different seasons.

245 patients with typhoid fever were admitted in university of Isfahan Medical Centers during the last 4 years are reported here in this study. The diagnosis was confirmed in each case by the history of the exposure physical examination, Widal seroreaction and blood culture test. The highest incidence of the disease occurred between 10-19 years of age, and mostly in summer months, during June, July, when the fresh fruits and vegetables are plentiful for consumption. There were 53 positive blood cultures for salmonella from 245 samples that were cultures. All patients were positive widal seroreaction with raising titer during the course of their illness. The complication were respectively as follow: hemorrhagic disorders 14% from which G.I. bleeding was the commonest form perforation 5% and myocarditis about 3% and other complications. These were arthritis, thromophelebitis and cholecystitis two cases of each are described here. It is worth of mentioning here the occurrence of hepatitis, osteomyelitis the two unusual complications of the disease in this communication.

The intensity of noise, heat and light were measured in 10 different groups of food processing plants with 3820 employees. Noise was measured in 265 working places and if the over-all noise was more than t.L.V. (90dbA), the octave band analysis was carried out. Effective temperature (E.t) or corrected effective temperature (C.E.t) were measured in 183 working places and air velocity relative humidity, radiant heat and worker's comfort were calculated. Illumination of 632 tasks was measured. Comparison of noise, heat and light measurements with the recommended standards by ISO, WHO, IES showed that 21% of the measured noise levels were above t.L.V., only E.T. or C.E.t. in 8% of the measurements met the standards. Illumination met the standards in only 3.5% of the measurements, 50% were less than 100 lux and 66% less than the recommended value for the specific tasks. Results are discussed and control measures are recommended.

Breeding places of A. Stephensi were studied in Bandar Abbas city, on Persian Gulf to determine the characteristics of breeding places and the larval density. The conventional standard dipper was used and all stages in ten dippers were considered as measuring scales. The study showed the presence of larvae in seven different types of breeding places which were: Barrels and pounds which were used as water reservoirs for housing projects; Some pits produced as the result of break making activities; Water remaining in wash basins and bathrooms of summer houses; Some small drainers; Open water reservoirs in government buildings; Barrels used as water reservoirs in some of the huts; Shallow wells. Although in all of the above breeding places larval density was found to be high (550 per 10 dippers), adult mosquitoes were rare. However since people do not like malathion spraying of their houses because of its smell, larvae control seems to be the best alternative for malaria control of that area. Larvicides, draining of stagnant water and other means can be sued to lower both the larvae and adult anopheles populations.
