Cement toxicity can cause various health issues, including skin, eye, and respiratory tract irritation, and allergic contact dermatitis. Here are an assessment on the response of humans under two conditions: polluted with cement Elma Labiod and Ferkane as non polluted region and the impact of temperature vis-versa between these two regions. Our work showed that cement perturbs the hematological and biochemical parameters of Elma Labiod habitant especially increased cancer cases (very high amount of platelets). Contrarily all data shown here was treated anonymously and obtained in real time...

L'exposition et l'utilisation des nanoparticules sont largement remises en cause par une prise de conscience récente de l'existence de risques potentiels mal connus. Ces nanoparticules ont en effet des propriétés et un comportement différent des autres particules à cause de leur taille très réduite. Elles sont caractérisées et classifiées selon des comportements particuliers et de nouveaux paramètres qui leurs sont propres. Pourtant, des particules fines, de taille plus importante, les nanoparticules, sont connues pour leur toxicité vis-à-vis de l'environnement et de l'organisme...

Eggshells have some organic membranes and contain a lot of CaCO3, although they are typically regarded as garbage. ES comprise roughly 95% calcium carbonate, and the ES membrane's fibrils are primarily made of proteins, around 10% of which are collagen (types I, V, and X).Due to the versatility of both calcium carbonate and collagen in many fieldssuch as medicine, pharmaceutic, alimentation and cosmetic. In this study, we used waste eggshell as raw material to extract calcium carbonate and collagen as bio and natural products, and in this study we gave an attempt to reduce waste eggshell,...
