  Environmental hormone pollutants are synthetic chemicals which can disturb endocrine systems in human and wildlife if they enter body. Many diseases have been related to environmental hormones ranging from hormone dependent cancers to low sperm quality and quantity, infertility, wildlife population decline, developmental abnormalities and many more disruptions. Many of these pollutants are generally originated from oil and petroleum products. Therefore, estimating the amount of environmental hormone contaminations in raw materials and products of petrochemical complexes can illustrate the amount of society exposure to those dangerous pollutants. This study has looked at one of the biggest petrochemical complex, Bandar-e-Imam petrochemical complex, in Iran in order to determination of the extent of environmental hormones` contamination in material used and produced there. Bandar-e-Imam petrochemical complex produces 6.1 million tons of different products (3.5 million tons such as light and heavy chains polyethylene, polypropylene, PVC, artificial plastic, aromatic compounds (benzene, xylene) etc) every year. From 158 ingredients or products (7546928.47 tons) studied in this paper, 30 of them (3871447.8 tons) possess at least one environmental hormone pollutant. The most and the least percentage of the number of environmental hormones belong respectively to used and produced materials in CA unit (50%) and EDU unit (8%). No significant difference (p>0.05) were observed between raw materials used and final products made in petrochemical complex regarding to environmental hormone pollution.

  Recent studies have shown that certain man-made compounds (including some pesticides and herbicide) through interfering with endocrine system, have the capability to induce developmental and reproductive abnormalities in humans and animals. Pesticides are currently being used in large scales in many developed and developing countries (including Iran), so this study has been conducted to determine the percentage of endocrine disruptor agents in pesticides used in Fars province. The results showed that more than 1,581,690 L of pesticides, in 86 different brands, have been used in Fars province during year 1380 and 25.93% (34 types) of them had at least one carcinogenic agents. At least 30 pesticides (711720 L, 44.99%) had one endocrine disruptor agent and therefore can be classified as environmental hormones or endocrine disrupting chemicals. The percentage of pesticides whom interfering with normal endocrine system activity were, 7.82% (66572 L), 4.54% (39975 L), 22.02% (348400 L), 5.12% (81000 L) and 21.18% (34500 L) of pesticides were antiestrogenic, antiandorgenic, antityroidic, antigonadotropin and anitestroid hormones, respectively. The results showed that about 50% of pesticides which currently being used in Fars province should be banned.
