BACKGROUND Prenatal exposure to organophosphorous (OP) pesticides has been found to be associated with adverse effects on child neurodevelopment, but evidence on potential effects induced by both prenatal and postnatal OP exposure in infants is limited. OBJECTIVES Our aim was to investigate the associations of both prenatal and postnatal OP exposure with birth outcomes and infant neurodevelop...

organophosphorous (op) pesticides are used frequently in agriculture, particularly in asian countries over the past decades. poisoning by these agents, either as acute or chronic in these nations, is a serious health problem. op pesticides residue in fruits and vegetables that may not induce early clinical features, could also affect the human health. therefore, medical and health professionals...

Organophosphorus (OP) pesticides are used in agriculture and several are registered for home use. As young children age they may experience different pesticide exposures due to varying diet, behavior, and other factors. We measured six OP dialkylphosphate (DAP) metabolites (three dimethyl alkylphosphates (DMAP) and three diethyl alkylphosphates (DEAP)) in urine samples collected from ~400 child...

BACKGROUND Animal studies have demonstrated that low paraoxonase-1 (PON1) status (i.e., low catalytic efficiency and/or low plasma PON1 activity) is associated with neurotoxic effects after exposure to several organophosphate (OP) insecticides. However, few human studies have investigated associations between PON1 status and intermediate end points, such as serum cholinesterase [butyrylcholines...

We measured organophosphorus (OP) pesticide exposures of young children living in an agricultural community over an entire year and evaluated the impact of agricultural spraying on exposure. We also examined the roles of age, sex, parental occupation, and residential proximity to fields. We recruited 44 children (2-5 years old) through a Women, Infants, and Children clinic. We collected urine s...

The recent Common Agricultural Policy (CAP) reform of the financial support mechanism for farms was introduced in 2005. According to this reform, the level of support that each farm receives is paid regardless of the current level of production. The decoupling of direct payments is expected to change production decisions, as farmers will change their mainly subsidy revenue maximization objectiv...
