Hydrobiology and Biological Analysis

The organisms of the aquatic biological community are considered good indicators of changes in the environment and can be called bioindicators. Our laboratory is able to analyze these organisms both qualitatively and quantitatively.

Cyanobacteria

In general and briefly, they can be defined as photosynthetic bacteria. Some are of interest to the pharmaceutical and agricultural markets, however, they can produce toxins that, when released in water, can cause damage to the health of animals and humans who ingest contaminated water. In addition, they can produce strong odor and unpleasant taste in the water. Hence the importance of monitoring the presence of cyanobacteria in water intended for consumption.

Phytoplankton

Popularly known as algae or microalgae, they represent the base of the aquatic marine or sweet food chain. The most representative groups of phytoplankton are diatoms and dinoflagellates, the latter being responsible for producing the famous “red tide” phenomenon. Monitoring the variation in the composition of the phytoplankton community helps to identify possible environmental impacts on the community from anthropic polluting sources, such as effluent releases.

Chlorophyll a, b, c and pheophytin a

Phytoplankton biomass can be indirectly determined through the concentration of photosynthetic pigments. The analysis of these pigments is done by spectrophotometry and is able to provide a faster response to the phytoplankton biomass present in the study environment.

Periphyton

Defined as a “complex community of algae, bacteria, fungi and animals, in addition to debris, adhered to submerged organic or inorganic substrates, living or dead”. Basically, we work with analysis of the peripheral algae. Because it is a community that lives fixed on some type of substrate, it becomes more susceptible to the action of predators, as well as to impacts from specific anthropic sources.

Zooplankton

They can be defined as aquatic animals that live “adrift” in marine and sweet environments. The composition of this community is well diversified, especially the groups of protozoa, rotifers and crustaceans. As with phytoplankton, monitoring the variation in zooplankton composition can assist in identifying possible environmental impacts on the community from anthropogenic polluting sources.

Ichthioplankton

The ichthyoplankton consists of the eggs and larvae of fish that live “adrift in aquatic marine and freshwater environments. The study of this community aims to obtain information about the distribution and abundance of eggs and fish larvae, having great importance in determining spawning periods and places. Such information is essential for the knowledge, maintenance and preservation of the species of this community, mainly for the fishing industry.

Parasitology

Realizamos estudos de presença/ausência de parasitas nocivos à saúde humana e que são passíveis de ocorrerem em águas destinadas ao consumo ou em solos.

Giárdia

Giárdia is a microscopic protozoan that parasites the intestines of mammals, including humans. The main risks of infection by Giárdia are given through the consumption of food contaminated by untreated water, self-infection (eg: contact with contaminated feces – mainly due to poor hand hygiene after changing contaminated baby diapers) or handling food inappropriately.

Cryptosporidium

Cryptosporidium is a protozoan responsible for cryptosporidiosis, which is an infection often associated with diarrhea in young individuals and prolonged gastroenteritis in immunodeficient people. The transmission of the disease can occur through person-to-person, animal-to-person contact or ingestion of contaminated water and food. Some studies recommend that treated water be filtered or boiled to make sure that oocysts resistant to the usual treatment methods (such as chlorination) are eliminated.

Helminths

Popularly known as worms, helminths are transmitted through contact with the contaminated food or place. Among the diseases caused by helminths, we can highlight ascariasis or roundworm, hookworm or yellowing and the geographic bug. In addition to good hygiene habits, it is recommended to avoid walking barefoot, as the soil may be infected with feces from contaminated animals.

Environmental Ecotoxicology

Ecotoxicological analyzes are able to provide information about an organism’s real response when exposed to an effluent or test solution. Given that the synergy between the physical and chemical characteristics of the sample is not noticeable when we analyze the elements separately, the toxicity analysis becomes essential to obtain a real result of how the biota reacts to this synergy between the elements. The analysis of the toxins released by the organisms, cyanobacteria in this case, tells us the toxic potential of water.

Acute Toxicity - Danio Rerio

Analysis of the mortality of the fish species Danio Rerio when exposed to an effluent in a time of 48 hours (static test). The results can be expressed in a qualitative (toxic or non-toxic) or quantitative (FT – toxicological factor; CENO – unobserved effect concentration; LC50 – lethal concentration at 50% of exposed organisms)

Cyanotoxins

Cyanotoxins are toxins produced by cyanobacteria and can be harmful to man. The effects vary according to the type and amount of toxin ingested, ranging from malaise to death.

Microcystin

Microcystin is a hepatotoxin produced by cyanobacteria (eg, microcystin and nodularin). They cause malaise, vomiting, headache and gastroenteritis. Episodes of microcystin ingestion were responsible for the death of fish, animals important to the farming industry, pets and humans (if it occurred in the state of Pernambuco).

Saxitoxina

Saxitoxin is a neurotoxin. Neurotoxins are substances that block the transmission of signals between two neurons, or between a neuron and its effector (a muscle, for example).
