[Pesticide impact on health: a study of tomato cultivation].

OBJECTIVE: In addition to water contamination, the presence of pesticide residues in food poses a risk to the population, being a serious public health problem in Brazil. With the purpose of getting a better understanding of this scenario, the use of pesticides in tomato crops in the State of Pernambuco, Brazil, was studied. METHODS: Questionnaires were applied to obtain social and environmental information as well as morbidity rates and additional data on rural workers involved in tomato plantations in two regions of Pernambuco, Brazil. RESULTS/CONCLUSIONS: The results obtained in the two studied regions show that there is a lack effective policies to both protect the health of rural workers who have to deal with pesticides and the environment which has already been severely damaged.

Effects of heavy industrial pollution on respiratory function in the children of Cubatao, Brazil: a preliminary report.

Under a cooperative agreement between New York University and the Environmental Protection Agency, and in collaboration with the University of Sao Paulo (USP), a study is ongoing in Cubatao, Brazil, to try to establish exposure-response relationships on the impact of specific industrial effluents on respiratory function in school-age children. Cubatao, located on the coast about 44 km from the city of Sao Paulo, is surrounded by U-shaped mountains (approximately 800 m) covered with subtropical forests. Its area is approximately 160 km2, and it has a population of approximately 90,000. The geography is such that it causes a consistent diurnal land-sea breeze pattern and the opposite during the night, with low dispersion of the air pollutants. In a small area (approximately 40 km2) against the mountains there is a concentration of over 20 large plants: oil refinery; iron and steel mill; fertilizer, cement, and gypsum production; coke kilns; and chemical, paint, and many other ancillary plants. During the 1988 school year, March through June, August through November, 600 six-year-old children, attending six different kindergarten schools, underwent monthly spirometry tests. Because the children live within a 500 m radius of their school, pollution monitors were located on each of the six schools. Particles were collected using dichotomous stacked filter units placed on 20 m towers to reduce the influence of dust from unpaved roads. The units use different pore size filters for coarse, 2 to 10 microns, and fine particles, (dp) less than 2 microns, and took separate samples for day and nighttime.(ABSTRACT TRUNCATED AT 250 WORDS)
