Abstract:
Several marine microalgae produce dangerous toxins very damaging to human health, aquatic ecosystems and coastal resources. These Harmful Algal Blooms (HABs) in recent decades seem greatly increased regarding frequency, severity and biogeographical level, causing serious health risks as a consequence of the consumption of contaminated seafood. Toxins can cause various clinically described syndromes, characterised by a wide range of symptoms: amnesic (ASP), diarrhoetic (DSP), azaspirazid (AZP), neurotoxic (NSP) and paralytic (PSP) shellfish poisonings and ciguatera fish poisoning. The spread of HABs is probably a result of anthropogenic activities and climate change, that influence marine planktonic systems, including global warming, habitat modification, eutrophication and growth of exogenous species in response to human pressures. HABs are a worldwide matter that requests local solutions and international cooperation. This review supplies an overview of HAB phenomena, and, in particular, we describe the major consequences of HABs on human health.

Types of Toxins
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
