Ecological and Human Health Risk Assessment of Pesticide Residues in Fish and Sediments from Vea Irrigation Reservoir

Potensi Aromaterapi Jeruk Purut (Citrus hystrix DC.) sebagai Adultisida terhadap Aedes aegypti (Linn.) Dewasa

“…3 Antinyamuk yang beredar di masyarakat umumnya terbuat dari bahan kimia sintetis, memiliki efek jangka panjang dapat menimbulkan mutasi, resistensi, serta residu yang berbahaya bagi manusia serta persisten di alam. 4,[5][6][7] Berdasarkan hal tersebut, berbagai upaya dilakukan untuk mencari alternatif pengganti insektisida kimiawi yang lebih ramah lingkungan dan aman bagi manusia. 8 Salah satu upayanya dengan pengembangan insektisida berbahan dasar alami yang berasal dari tumbuhan.…”

Ultrasensitive Detection of Organophosphorus Pesticides Using Single-Molecule Conductance Measurement

“…Organophosphorus pesticides (OPs) have been used extensively to eradicate insects in agricultural areas across the world in recent decades. , And OPs are an ensemble of strictly regulated toxic compounds that have harmful effects on humans and animals when the residues are in low amounts of 55.2 pM (10 –12 mol/L). , The toxic effects of OPs make them inhibit the activity of acetylcholinesterase, which causes interruption of neurotransmitter transmission and eventually death. − Although colorimetric systems were widely employed to detect OPs, the severe interference of sensitivity and selectivity about OPs caused by color limited their applications in practical samples. − To overcome the interference by color, lots of efforts had been made in the past years, such as microarray, , capillary electrophoresis, liquid chromatography, nuclear magnetic resonance, and mass spectrometry . However, most of these methods required time-consuming sample pretreatment, the use of other materials for signal amplification, low sensitivity, and sophisticated instrument manipulation.…”
