IDENTIFICATION OF MICROPLASTICS PRESENT IN POLYTHENE-SACHET WATER SIMPLY EXPOSED TO SUNLIGHT

ABSTRACT Polythene and PVC are polymers used in production of packaging materials which are frequently used for food and water. Antioxidants, stabilizers, plasticizers, lubricants, antimicrobials, anti- static and anti-blocking agents, “slips,” or heat resistance agents are usually incorporated during the production of these packaging materials to improve functionality. A wide variety of synthetic and naturally occurring polymers absorb solar ultraviolet radiation and undergo photolytic, photooxidative, and thermooxidative reactions that result ...

TOXIC PROFILE OF THE METHANOL LEAF EXTRACT OF SENNA SIAMEA AND ITS ANTIOXIDANT PRPOPERTIES

ABSTRACT Medicinal plants have been assumed to be good in detoxifications because they contain bioactive compounds capable of doing this. However, some plants are very toxic to both humans and animals with the potential of damaging certain organs in the body. Many plant- derived  substances,  collectively termed  â€œphytochemicals,”  are  becoming  increasingly known for their antioxidant activity. This study is aimed at investigating the toxic and as well as the antioxidant ...
