Presencia de agroquímicos en ecosistemas acuáticos de zonas costeras y análisis preliminar del riesgo ambiental.
From 1992-1997 Costa Rica imported about 41 million kg of pesticide active ingredients. The total quantity imported in 1997 was 61% higher than the one imported in 1992. The kilograms of a.i. utilized per hectare of cultivated land also increased during the mentioned period. Seventeen a.i. composed...
