This First Conference of Natural Resources and Development called Food, water and energy security: integrated science for sustainability is an opportunity to connect the scientific and academic world to the governmental area and the private sector. The Conference aims to be a space to disseminate updated knowledge regarding the food, water and energy security in the frame of sustainability.

This Conference, to be held in Viña del Mar, Chile, from November 25 until 28 is supported by Journal of Natural Resources and Development and is jointly organized by the United Nations Environment Programme (UNEP), and the Center for Natural Resources and Development (CNRD); an international network created to involve different universities of the world in the Millennium Development Goals (MDGs) of the United Nations. Key topics related to the MDGs are poverty reduction and safe food supplies, social and cultural development, access to basic resources and shelter, integrated water resources management, land use dynamics, biodiversity, energy efficiency and renewable resources among others. All the topics will also be covered in the Conference.

Attention! The call for papers and posters is open to scientists and researchers from the academic or private sector; this means that we welcome professors, students, entrepreneurs, professionals, researchers and all other members of the public, private or educational area working on topics related to the conference frame.

Abstract

The organophosphorus (OP) pesticide (malathion) is used heavily for many crops such as vegetable and cotton to control serious key insecticide in many areas of Egypt. This study has focused on the effect of malathion on aquatic environment and aquatic organisms. The experimental work was carried out using malathion at different dosage of water lasted 96h and was carried out undertaken laboratory conditions. It evaluated the sensitivity of organic toxic waste and their purification techniques for common carp, Cyprinus carpio by determining enzymes activity as biomarker indicators in various organs of the studied fish.

The results showed that exposure to malathion caused a significant increase in enzyme activity and total protein contents in the investigated tissues and inhibition of brain and liver acetylcholinesterase (AChE). Moreover, among the tissues studied, it appeared that the brain, gills and liver were more sensitive to pollution and seemed to be the most appropriate tissues to monitor water pollution by OP pesticides. In this context for environmental biomonitoring, the evaluation of toxic waste purification can be done to assess sensitivity of aquatic organism in recycling water to meet national goals and environmental safety.
