Marine debris pollution can threaten the sustainability of natural resources in coastal regions ecosystem. is worldwide issue now and Indonesia considered as a second biggest polluter plastic to world ocean. Massive efforts have been applied tackle marine debris, both by central government provincial level, manage these problems minimize impact on Various types mangrove seagrass ecosystem cover...

TiO2/ZnO films grown by atomic layer deposition (ALD) demonstrated nanotribological behaviors using scratch testing. TEM profiles obtained an amorphous structure TiO2 and nanocrystalline structure ZnO, whereas the sample has significant interface between the TiO2/ZnO films. The experimental results show the relative XRD peak intensities are mainly contributed by a wurtzite oxide ZnO structure a...

Fibronectin immobilized to plastic tubes binds soluble C1q with a Kd of 82 +/- 2.6 nM. The binding of fibronectin to C1q is relatively insensitive to pH but is sensitive to ionic conditions. C1q covalently bound to Sepharose selectively binds cellular fibronectin produced by a hamster fibroblast cell line. The globular head regions of C1q have no effect on the binding of C1q to fibronectin but ...

While the scarcity of up-to-date data on beach litter contamination in the Caribbean has been stressed in several recent studies, we here point to the even greater paucity of published work on litter in mangroves and on the shallow tropical seafloor. During collection of baseline data on beach litter contamination on the Southeastern Caribbean island of Bonaire (Debrot et al. Mar. Poll. Bull., ...

The amount and characteristics of plastic waste in the environment are closely monitored with regular expansion their collection to smaller debris sizes new compartments, such as atmosphere, soil even food. These data, subject constant re-evaluation, necessary assess threat that particles pose. In this article, we take stock most recent measurements size distribution on ocean surface. We confro...

The issues related to the disposal of consumer waste are great importance in ensuring environmental safety not only a particular region, but also entire planet as whole. article deals with problem pollution small rubbish (cigarette-ends, plastic and glass bottle caps, etc.). To solve this problem, it is proposed train birds Corvidae family (Crows) collect debris then hand over apparatus for exc...

in order to ensure the safety of parenterals, international pharmacopoeias and national standards have set up stringent guidelines and standards. particulate con- tamination is a potential health risk caused by intravenous injection of particles large enough to potentially clog the small arteries. particles could be produced through manufacturing and packaging or even dispensing of the pharmace...

Plastic debris causes extensive damage to the marine environment, largely due to its ability to resist degradation. Attachment on plastic surfaces is a key initiation process for their degradation. The tendency of environmental marine bacteria to adhere to poly(ethylene terephthalate) (PET) plastic surfaces as a model material was investigated. It was found that the overall number of heterotrop...

When searching for prey, animals should maximize energetic gain, while minimizing energy expenditure by altering their movements relative to prey availability. However, with increasing amounts of marine debris, what once may have been 'optimal' foraging strategies for top marine predators, are leading to sub-optimal diets comprised in large part of plastic. Indeed, the highly vagile Laysan alba...

Concern about marine litter has been rising in the last decades, triggered by the discovery of the great mid-ocean garbage patches. The Mediterranean Sea is strongly affected by the presence of floating litter, as it has a very high amount of waste generated annually per person that eventually ends up in its waters, with plastic objects accounting for a large percentage of all manmade debris. I...
