HYDROCARBONS AND ORGANOCHLORINE PESTICIDES IN SOILS OF THE URBAN ECOSYSTEM OF CHILLÁN AND CHILLÁN VIEJO, CHILE

Although traditional soil use in Chillán and Chillán Viejo is agricultural, both cities have seen their surrounding areas expand and change drastically. Economic activities have increased, including phytosanitary companies and petroleum derivatives used in agriculture and transport. This has had a l...
