Classifying Matter by Composition03:35

Classifying Matter by Composition

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

Types of Reports II: Incident or Occurrence Report

1.3K
An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.
Purposes:
In the healthcare industry, reports play a crucial role in documenting incidents within an agency. The primary objective of these reports is to ensure patient safety, uphold the...

Subatomic Particles

114.0K
Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.

The Nucleosome Core Particle02:10

The Nucleosome Core Particle

14.6K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

Composite Bodies00:55

Composite Bodies

1.4K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

Composition of Blood01:22

Composition of Blood

12.7K
The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...

Area of Science:

  • Environmental Science
  • Marine Pollution
  • Ecotoxicology

Background:

  • Antifouling paints are crucial for marine vessels but can release harmful particles.
  • Patos Lagoon estuary (PLE) in Southern Brazil is a vital aquatic ecosystem potentially impacted by these particles.
  • Understanding the sources and fate of antifouling paint particles (APPs) is essential for environmental protection.

Purpose of the Study:

  • To identify and assess the sources, occurrence, composition, and dynamics of antifouling paint particles (APPs) in the Patos Lagoon estuary.
  • To evaluate the potential environmental risks associated with APP contamination in the studied region.
  • To provide recommendations for mitigating APP pollution in Brazilian aquatic systems.

Main Methods:

  • Identification of potential APP sources in ten estuarine areas, including boatyards, a marina, and fishing harbors.
  • Sediment sampling and analysis to quantify APP levels (μg/g).
  • Settling experiments and hydrodynamic analysis to understand APP mobility and deposition.

Main Results:

  • High and heterogeneous concentrations of APPs (130–40,300 μg/g) were found, with boatyards and marinas identified as significant sources.
  • Artisanal fishing harbors may contribute significantly as diffuse sources, while boatyards and marinas act as 'hotspots'.
  • APP mobility is influenced by particle characteristics (size, shape, density) and estuarine hydrodynamics, leading to varied distribution patterns.

Conclusions:

  • Improperly disposed APPs, containing trace metals and biocides, pose a significant contamination risk to aquatic environments.
  • Brazil faces an environmental challenge due to a lack of specific legislation and inefficient control mechanisms for APP pollution.
  • Urgent improvements in boat maintenance practices are needed to reduce the continuous release of APPs into aquatic systems.
