Harmful Algal Blooms

2016
This project-based learning assignment is designed for high school students and takes a prevalent problem found in nature and educates students on the causes and effects of harmful algal blooms. It encourages students to exercise ingenuity in order to develop a possible solution to this problem.

Harmful algal blooms and their eco-environmental indication

Chemosphere, 2021
Harmful algal blooms (HABs) in freshwater lakes and oceans date back to as early as the 19th century, which can cause the death of aquatic and terrestrial organisms. However, it was not until the end of the 20th century that researchers had started to pay attention to the hazards and causes of HABs. In this study, we analyzed 5720 published literatures

Harmful algal blooms in Iowa

2023
Many environmental factors interact to form HABs. The largest driver of growth for HABs is nutrient pollution, a long-standing issue in Iowa due to the agriculturally dominated landscape accompanied by a lack of protective regulations and enforcement.

Harmful algal blooms in inland waters

Nature Reviews Earth & Environment
Harmful algal blooms can produce toxins that pose threats to aquatic ecosystems and human health. In this Review, we outline the global trends in harmful algal bloom occurrence and explore the drivers, future trajectories and potential mitigation strategies.

Models of harmful algal blooms

Limnology and Oceanography, 1997
Models used to study harmful algal blooms are a subset of those used to examine more general planktonic processes. Most models have been heuristic, examining the likelihood of certain processes generating a harmful algal bloom. Several models have been more closely coupled to field data and have been used to gain insights into the dynamics underlying ...

Screening of surfactants for harmful algal blooms mitigation

Marine Pollution Bulletin, 2004
Screening experiments were conducted in order to find promising synthetic surfactants for harmful algal blooms (HABs) mitigation. The chemically synthesized surfactant cocamidopropyl betaine (CAPB) showed characteristics of relatively high inhibition efficiency, high biodegradability and low cost.

Harmful Algal Blooms (HABs)

2018
Harmful algal blooms (HABs) are serious biological nuisances and become a global epidemic. This is primarily flagellate events, causing mass mortality, physiological impairment or other negative in situ effects. HABs are increasing their frequency, persistence, regional coverage/spatial extent and economic impact worldwide in recent decades as a result

Global warming and cyanobacterial harmful algal blooms

2008
The Earth and the oceans have warmed significantly over the past four decades, providing evidence that the Earth is undergoing long-term climate change. Increasing temperatures and changing rainfall patterns have been documented. Cyanobacteria have a long evolutionary history, with their first occurrence dating back at least 2.7 billion years ago ...
