Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Effects of Chemicals: Overview

Effects of Chemicals: Overview

Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Radical Substitution: Halogenation of Alkanes and Alkyl Substituents

Radical Substitution: Halogenation of Alkanes and Alkyl Substituents

In the presence of heat or light, alkanes react with molecular halogens to form alkyl halides by a substitution reaction called radical halogenation. This reaction has three steps: initiation, propagation, and termination, as seen in the radical chlorination of methane to produce methyl chloride.
In the initiation step of the reaction, the chlorine molecule undergoes homolytic cleavage in the presence of light or heat, forming two highly reactive chlorine radicals. Propagation occurs in two...

Chemical Agents for Microbial Control

Chemical Agents for Microbial Control

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Summary

Global emission estimates for Dechlorane Plus (DP), a flame retardant, were developed. The high emission scenario, totaling 3.2 tons/year, aligns with Arctic measurements, suggesting its higher probability.

Environmental Chemistry
Atmospheric Science
Chemical Engineering

Background:

Dechlorane Plus (DP) is a widely used chlorinated flame retardant.
Its presence in global environmental media necessitates accurate emission data.
DP is often used as a replacement for regulated flame retardants.

Purpose of the Study:

To develop detailed global atmospheric emission scenarios for Dechlorane Plus.
To provide essential data for environmental modeling studies.
To estimate DP emissions based on production, usage, and disposal.

Main Methods:

Development of two distinct global atmospheric emission scenarios (low and high).
Geographical distribution of emissions based on production and usage data.
Implementation of emission estimates in the Danish Eulerian Hemispheric Model.
Validation of model predictions against Arctic measurements.

Main Results:

Estimated DP emissions range from 0.02 tons/year (low scenario) to 3.2 tons/year (high scenario).
The high emission scenario's predicted concentrations align with Arctic background measurements.
The low emission scenario significantly underestimated measured Arctic concentrations (by over 100-fold).

Conclusions:

The high emission scenario for Dechlorane Plus is considered most probable.
Accurate emission inventories are crucial for understanding the environmental fate of flame retardants.
This study provides vital data for assessing DP's global environmental impact.
