Summary
Harmful algal blooms (HABs) are increasing due to environmental changes. Aerosolized HAB toxins pose respiratory risks, especially when combined with air pollution, highlighting the need for further research to ensure public safety.
Area of Science:
- Environmental Science
- Toxicology
- Public Health
Background:
- Algal and cyanobacterial blooms are increasing globally due to climate change and eutrophication.
- These blooms release airborne algae, cyanobacteria, and toxins, posing risks to human health.
- Respiratory distress is linked to exposure to aerosols containing harmful algal bloom (HAB) toxins.
Purpose of the Study:
- To review the generation of aerosolized HABs.
- To investigate their environmental responses.
- To assess associated human health risks.
Main Methods:
- Literature review of studies on aerosolized HABs, environmental factors, and health impacts.
- Analysis of atmospheric processing of HAB toxins.
- Examination of co-morbid factors exacerbating health risks.
Main Results:
- Airborne algae, cyanobacteria, and their toxins are widespread.
- Atmospheric processing can alter HAB toxin potency.
- Inhalation of aerosolized HAB toxins presents a significant health risk, particularly with co-exposure to pollutants.
Conclusions:
- Increased frequency and extent of HABs necessitate understanding airborne risks.
- Further research on toxin transformation and community composition is crucial for public safety.
- Mitigation strategies are needed to address the growing public health threat from aerosolized HABs.

01:28Overview of Algae
195
The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...

108
Cyanobacteria are a diverse group of oxygenic, phototrophic bacteria that played a pivotal role in converting Earth’s atmosphere from anoxic to oxygen-rich billions of years ago. They exhibit remarkable morphological diversity, ranging from unicellular forms to filamentous types, with cell sizes varying between 0.5 μm and 100 μm. Cyanobacteria are classified into five groups: Chroococcales (unicellular, dividing by binary fission), Pleurocapsales (unicellular, dividing by...

Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

01:36Types of Toxins
2.0K
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.
