This paper examines the impact of two popular solid waste programs on the percent recycled of several different materials found in the residential solid waste stream. We examine a unique, national, household-level data set containing information on the percent recycled of five different materials: glass bottles, plastic bottles, aluminum, newspaper, and yard waste. We find that access to curbsi...

BACKGROUND Bisphenol A (BPA) is a high-production-volume chemical commonly used in the manufacture of polycarbonate plastic. Low-level concentrations of BPA in animals and possibly in humans may cause endocrine disruption. Whether ingestion of food or beverages from polycarbonate containers increases BPA concentrations in humans has not been studied. OBJECTIVES We examined the association bet...

The mother of a 5-week-old term infant brings the infant to the pediatrician’s office, along with a plastic milk bottle used to feed the baby. The bottle has splotches of red-pink material on the inside (Fig. 1). She wants to know what is happening to the milk in the bottle. The mother has been breastfeeding and has recently been transitioning to pumped breast milk in preparation for returning ...

Did you know that plastic waste is so widespread across our planet it can be found even in the far north, Arctic Ocean? Plastic ends up environment many different ways, and researchers are trying to figure out how this pollution affects animals plants living environments contain waste. Here comes a message bottle from North Pole, telling story about tiny pieces of Ocean. How possible for reach ...

BACKGROUND Communities living in developing countries as well as populations affected by natural or man-made disasters can be left at great risk from water related diseases, especially those spread through the faecal-oral route. Conventional water treatments such as boiling and chlorination can be effective but may prove costly for impoverished communities. Solar water disinfection (SODIS) has ...

Suspensions of the faecal indicator bacteria Escherichia coli and Enterococcus faecalis were incubated in full sunlight in plastic bottles containing either (i) air-equilibrated (oxygenated) water or (ii) anaerobic (deoxygenated) water. A rapid decrease in cfu ml-1 was observed for actively growing and stationary phase cells of both types of faecal bacteria when illuminated under aerobic condit...

Forensic experts in uncovering the truth of a case must go through identification, documentation, and collection evidence. Sometimes at crime scene, lip prints are found on surface an object such as mouth plastic bottle. Lip print research bottle mouths was carried out for 1, 3 7 days. There 21 samples with details controls, 6 first day, 3rd 7th day. DNA extraction using DNAzol, quantification ...

Almost all fast-moving consumer goods (FMCG) use plastic-based packaging because it is easy to shape, can be colored, and raw materials are cheap. Aqua bottle uses PET (Polyethylene Terephthalate) plastic, the problem occurs when disposable becomes waste, difficult decompose, complex recycling process resulting in environmental pollution even become one of factors climate crisis. presents Life ...

Component testing indicates that overheating in tropical buildings could be reduced using walls built from upcycled sand-filled plastic bottles, which also reduces building costs and prevents waste polluting the environment. It is not yet known, however, how these bottle-composite influence thermal comfort dwellings in-situ. This study presents world's first in-situ measurement of indoor temper...
