This study assessed chemical safety management in academic laboratories in Hargeisa, Somaliland. Hence, this study aims to assess the level of chemical laboratory safety practices, chemical inventory and record management, and chemical waste procedures in laboratories. This study collected data from three academic institutions using a mixed method…

Exposure to heavy metals has been associated with affecting children's neurodevelopment, particularly increasing the risk of developing attention-deficit hyperactivity disorder (ADHD). The current exploratory study aims to investigate potential associations between presence of 15 different heavy metals in urine and ADHD. A total of 190 urine…

The research aims to reveal the awareness of children's parents about the hazards of their children's toys from the age groups (1-9 years). To examine the extent of their awareness of toy hazards and assess their attitudes towards them, the "case study" method was used. A survey was also built on the hazards of children's toys for this…

As ecological globalization intensifies, rural waste recycling and management has become a global concern. China's proactive efforts are significant for revitalizing domestic rural ecosystems, offering valuable insights into global environmental governance. The rampant dumping and informal processing of hazardous waste in rural China pose severe…

Introduction: Heavy metals such as Lead (Pb) and Mercury (Hg) can affect adipose tissue mass and function. Considering the high prevalence of exposure to heavy metals and obesity in Mexico, we aim to examine if exposure to Pb and Hg in adolescence can modify how fat is accumulated in early adulthood. Methods: This study included 100 participants…

The aseptic technique is essential for minimizing contamination in cell and tissue culture. However, biomedical science undergraduates in Universiti Putra Malaysia face challenges in acquiring hands-on learning experience on proper aseptic techniques due to inadequate facilities, which decreases learning interest and efficiency. To address this,…

Background: The evidence base for the regulatory assessment of endocrine-disrupting chemicals (EDC) has proved very controversial to define. The EU has been a first mover and--after years of discussions and conflicts--adopted criteria for the pesticide and biocide sectors in 2018. Key points: The article reviews alternative regulatory options and…

Chemicals are characteristic of chemistry education practices at all educational levels. The aim of this study is to explore teachers' didactic rationales when reasoning about the use of chemicals in their teaching practice. Experienced upper secondary chemistry teachers in Sweden were interviewed about their considerations regarding why, when,…

Purpose: Despite hazardous consequences, the use of fertilizers and pesticides has been exceptionally high, mainly to increase crop yield. Socio-economic factors have been explored to understand the inability to curb its overuse; however, literature on psychological factors affecting farmers' decision-making is very scarce. Psychological factors…

Within the scope of the current study, the researchers developed activities for middle school students to raise their awareness on the harm of plastics and microplastics, which are detrimental to nature and living things. In addition, through the activities developed, the study aimed to provide students with knowledge of and experience with…

Drug take-back system provides a legal, safe and eco-friendly avenue to appropriately dispose of unwanted medicines, contributing to both environmental sustainability and reducing medication misuse. This study designed and implemented a brief educational intervention, which took <1 min on average, to enhance awareness of community residents…

Inuit communities in Northern Quebec (Canada) are exposed to environmental contaminants, particularly to mercury, lead and polychlorinated biphenyls (PCBs). Previous studies reported adverse associations between these neurotoxicants and memory performance. Here we aimed to determine the associations of pre- and postnatal exposures to mercury, lead…

This study aims to evaluate the laboratory safety perception, awareness and attitude of undergraduates toward the chemistry teaching laboratory by means of a self-administered questionnaire. The survey contains a sample size of 959 undergraduates in Tianjin University of Technology involving four schools. Instrument reliability and validity are…

Children are exposed to many trace elements throughout their development. Given their ubiquity and potential to have effects on children's neurodevelopment, these exposures are a public health concern. This study sought to identify trace element mixture-associated deficits in learning behavior using operant testing in a prospective cohort. We…

The aim of this study is to provide training for science teachers on batteries, areas of use of batteries, types of batteries, things that should be paid attention to while using batteries, waste batteries, and collection, handling, recovery and/or disposal of waste batteries, and help teachers receiving the training to raise awareness among grade…
