"Summary: Computational Toxicology: Methods and Applications for Risk Assessment is an essential reference on the translation of computational toxicology data into information that can be used for more informed risk assessment decision-making. This book is authored by leading international investigators who have real-world experience in relating computational toxicology methods to risk assessment. Key topics of interest"

"This first comprehensive treatment of the subject for more than a decade includes the latest research on nanoparticle toxicology. The practical handbook addresses all areas where toxic mixtures are encountered, from environmental via occupational to medical settings, giving special consideration to air and water, and to the specific requirements for study design in mixture toxicology. While no extensive prior knowledge or toxicological experience is required, the practice-oriented case studies and examples in the second part make this the ideal companion for the professional toxicologist in industry or healthcare institutions with little time for academic study."

"Environmental toxicology is the third volume of a three-volume set on molecular, clinical and environmental toxicology that offers a comprehensive and in-depth response to the increasing importance and abundance of chemicals of daily life. By providing intriguing insights far down to the molecular level, this three-volume work covers the entire range of modern toxicology with special emphasis on recent developments and achievements. "

"Physiologically-based pharmacokinetic (PBPK) modeling is becoming increasingly important in human health risk assessments and in supporting pharmacodynamic modeling for toxic responses. Organized by classes of compounds and modeling purposes so users can quickly access information, this is the first comprehensive reference of its kind.This book presents an overview of the underlying principles of PBPK model development. Then it provides a compendium of PBPK modeling information, including historical development, specific modeling challenges, and current practices for, halogenated alkanes, alkene and aromatic compounds, reactive vapors in the nasal cavity, alkanes, oxyhydrocarbons, and related compounds, pesticides and persistent organic pollutants, dioxin and related compounds, metals and inorganic compounds, drugs, antineoplastic agents, perinatal transfer, mixtures, dermal exposure models."

"Penelitian ini bertujuan untuk mensintesis nano-komposit Ag/TiO2 untuk dikaji kemampuannya dalam mendegradasi mikroplastik dalam air, dilanjutkan dengan memvariasikan konsentrasi serta ukuran dari partikel mikroplastik sebagai polutan di dalam air minum. Mikroplastik polietilena dipilih sebagai sampel pada penelitian ini. Variasi konsentrasi mikroplastik yang digunakan yaitu 100, 500, dan 1000 ppm dengan ukuran partikel awal 100-150 mikrometer. Sedangkan variasi ukuran mikroplastik yang digunakan yaitu 100-125, 125-150, dan 150-250 mikrometer dengan konsentrasi awal 100 ppm. Pengaduk magnetik digunakan pada kecepatan putar 2000 rpm selama proses irradiasi dengan lampu UV. Penambahan dopan Ag memberikan efek yang cukup baik dalam mendegradasi mikroplastik, dimana persentase degradasi mencapai 100% dalam waktu 120 menit irradiasi pada konsentrasi awal 100 ppm dan ukuran partikel 100-150 mikrometer. Dengan konsentrasi awal 100 ppm diperoleh persen degradasi terbaik pada ukuran partikel 125-150 mikrometer, dimana degradasi 100% dicapai pada waktu irradiasi selama 90 menit.

The aim of this research is to synthesize Ag/TiO2 nano-composites to study their ability to degrade microplastics in water, followed by varying the concentration and size of microplastic particles as pollutants in drinking water. Polyethylene microplastics were selected as samples in this study. The variation of microplastic concentrations used are 100, 500, and 1000 ppm with an initial particle size of 100-150 micrometers. While the microplastic size variations used are 100-125, 125-150, and 150-250 micrometers with initial concentrations of 100 ppm. Magnetic stirrers are used at a rotational speed of 2000 rpm during the irradiation process with a UV lamp. The addition of Ag dopant has a fairly good effect in microplastic degradation, where the percentage of degradation reaches 100% within 120 minutes of irradiation at an initial concentration of 100 ppm and particle size of 100-150 micrometers. With an initial concentration of 100 ppm obtained the best percent degradation at particle size 125-150 micrometers, where 100% degradation was achieved at 90 minutes of irradiation."
