β-cyclodextrin (β-CD) is a good host for the encapsulation of fennel and basil essential oils (FEO BEO, respectively) formation inclusion complexes (ICs) using co-precipitation method. According to results GC/MS analysis conducted in this study, monoterpenes monoterpenoids were dominant chemical groups total FEO, while these two occurred along with sesquiterpenes sesquiterpenoids. The presence compounds from both EOs was validated FT-IR spectra ICs, which indicated successful complexation. Analyses SPME/GC-MS showed continuous emission volatiles over 24 h ICs. Under SEM, particles ICs appeared have rectangular or rhomboid morphology few aggregates. insecticidal properties β-CD tested on Colorado potato beetle (CPB) as model pest. complex FEO altered developmental dynamic body mass CPB. initial increase proteolytic activity CPB larvae fed plants sprayed not maintained long, efficacy treated remained line that control larvae. Future investigations will focus manipulating volume used treatment duration optimal potential application.

Exposure science is evolving from its traditional "after the fact" and "one chemical at a time" approach to forecasting exposures rapidly enough keep pace with constantly expanding landscape of chemicals exposures. In this article, we provide an overview approaches, accomplishments, plans for advancing computational exposure within U.S. Environmental Protection Agency's Office Research Development (EPA/ORD). First, characterize universe in commerce environment, carefully curated, web-accessible resource has been created. This DSSTox database unambiguously identifies more than 1.2 million unique substances reflecting potential environmental human includes computationally accessible links each compound's corresponding data resources. Next, EPA developing, applying, evaluating predictive models. These models increasingly rely on data, tools like quantitative structure activity relationship (QSAR) models, machine learning/artificial intelligence timely efficient prediction (and associated uncertainty) thousands time. Integral modeling effort, developing resources across continuum that application high-resolution mass spectrometry (HRMS) non-targeted analysis (NTA) methods providing measurement capability scale number commerce. research efforts are integrated well-tailored support population assessment prioritize as critical input risk management. addition, forecasts will allow wide variety stakeholders explore sustainable initiatives green chemistry achieve economic, social, prosperity protection future generations.
