Comparative acute toxicity of two phytosanitary molecules, lambda-cyhalothrin and acetamiprid, on Nile Tilapia () juveniles.

This study aimed to compare the toxicity for fish of two active ingredients (lambda-cyhalothrin-20 g L, a pyrethroid, and acetamiprid-15 g L, a neonicotinoid) which are components of a commercial insecticide (Acer 35 EC) used in cotton crop in many West African countries. The juveniles of (4.01 ± 0.

Exposure assessment of operators to pesticides in Kongou, a sub-watershed of Niger River valley.

The use of pesticides in horticultural sector in Niger has become an integral part of modern agriculture. Nevertheless, their inappropriate use can generate negative health effects to operators. A study was carried out among Kongou farmers in order to assess their potential dermal exposure (PDE).

Occurrence of Acetamiprid Residues in Water Reservoirs in the Cotton Basin of Northern Benin.

An Ultra performance liquid chromatography (UPLC) coupled to UV detection method was developed to determine acetamiprid residues in water reservoirs of northern Benin, close to cotton fields. The quantification limit of this method was 0.2 µg L acetamiprid in water, its precision ranged between 8% and 22%, and its trueness between 99% and 117% (for concentrations ranging from 0.

Assessment of Tomato (Solanum lycopersicum L.) Producers' Exposure Level to Pesticides, in Kouka and Toussiana (Burkina Faso).

To assess producers' exposure level to pesticides in vegetable production in Burkina Faso, a study was carried out in 2016 and 2017 among 30 tomato producers in the municipalities of Kouka and Toussiana. Eighteen (18) commercial formulations were identified, with more than 50% of pesticides destined for cotton production. Eleven active substances have been identified and the most frequently used are λ-cyhalothrin (35%), acetamiprid (22%) and profenofos (13%).

Risk Assessment of Florists Exposed to Pesticide Residues through Handling of Flowers and Preparing Bouquets.

Flowers are frequently treated with pesticides and, as a result, florists handling daily a large number of flowers can be exposed to pesticide residues. A study was conducted among twenty volunteer florists located in Namur Province and in the Brussels Capital Region of Belgium in order to assess their potential dermal exposure to dislodgeable pesticide residues transferred from flowers to hands. Two pairs of cotton gloves were worn during two consecutive half days while handling flowers and preparing bouquets (from min 2 h to max 3 h/day).
