Effective voltammetric tool for Nano-detection of triazine herbicide (1-Chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine) by naphthalene derivative.

The development and operation of a nanosensor for detecting the poisonous 1-chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine (Atrazine) are described in this study for the first time. The carbon electrode (CE) surface was modified with cysteine-substituted naphthalene diimide to create this sensitive platform. The developed nanosensor (NDI-cys/GCE) was evaluated for its ability to sense Atrazine using differential pulse voltammetry and cyclic voltammetry. To achieve the best response from the target analyte, the effects of several parameters were examined to optimize the conditions. The cysteine-substituted naphthalene diimide significantly improved the signals of the Atrazine compared to bare GCE due to the synergistic activity of substituted naphthalene diimide and cysteine molecules. Under optimal conditions, atrazine detection limits at the (NDI-cys/GCE) were reported to be 94 nM with a linear range of 10-100 µM. The developed sensing platform also showed positive results when used to detect the atrazine herbicide in real tap water, wastewater, and milk samples. Furthermore, a reasonable recovery rate for real-time studies, repeatability, and stability revealed that the developed electrochemical platform could be used for sample analysis.

Ecological effects, remediation, distribution, and sensing techniques of chromium.

Chromium is detected in most ecosystems due to the increased anthropogenic activities in addition to that developed from natural pollution. Chromium contamination in the food chain results due to its persistent and non-degradable nature. The release of chromium in the ecosystem accretes and thereafter impacts different life forms, including humans, aquatic and terrestrial organisms. Leaching of chromium into the ground and surface water triggers several health ailments, such as dermatitis, eczematous skin, allergic reactions, mucous and skin membrane ulcerations, allergic asthmatic reactions, bronchial carcinoma and gastroenteritis. Physiological and biological treatments for the removal of chromium have been discussed in depth in the present communication. Adsorption and biological treatment methods are proven to be alternatives to chemical removal techniques in terms of cost-effectiveness and low sludge formation. Chromium sensing is an alternative approach for regular monitoring of chromium in different water bodies. This review intended to explore different classes of sensors for chromium monitoring. However, the spectrochemical methods are more sensitive in chromium ions sensing than electrochemical methods. Future study should focus on miniaturization for portability and on-site measurements without requiring a large instrument provides a good aspect for future research.

Apparel Consumption and Embodied Experiences of Gay Men and Transgender Women in India: Variety and Ambivalence, Fit Issues, LGBT-Fashion Brands, and Affordability.

The purpose of this study was to explore Indian LGBT individuals' apparel consumption practices and embodied experiences related to fashion, style, and the body. Specifically, our research questions were these: What are Indian LGBT individuals' experiences like when navigating the fashion system, and how do they experience their own embodiment in what they wear and how they appear? A qualitative, phenomenological approach was used to answer the research questions. Three gay men and seven transgender women responded to a solicitation for participation and completed a semistructured interview. In our data analysis, we established four themes that relate to two larger areas of emphasis: embodiment and the fashion system. Regarding embodiment, participants related many experiences with their bodies, including (a) variety and ambivalence with bodily practices and (b) difficulty with clothing fit. The other themes centered around knowledge and desires related to the fashion system. Within the fashion system, participants expressed (a) fashion brand awareness and a need for LGBT-centered brands and (b) affordability as a barrier to clothing purchase. Overall, the essence of fashioning one's body as a transgender woman or gay man in India is that, while there has been a significant amount of gender oppression in India, these participants were interested in and desired gender-neutral or LGBT-focused brands.
