Summary
Engineered nanomaterials (NPs) pose health and environmental risks due to their unique size, potentially causing cytotoxicity and genotoxicity. Comprehensive research on NP toxicity via various exposure routes is crucial for safe clinical applications and societal impact.
Area of Science:
- Nanotechnology
- Environmental Health
- Toxicology
Background:
- Nanotechnology is a rapidly growing field with increasing use of engineered nanomaterials (NPs) in biomedical applications.
- NPs exhibit unique properties at the nanoscale, differing significantly from their bulk counterparts.
- Potential risks to human health and the environment necessitate careful toxicity assessment before clinical use.
Purpose of the Study:
- To review the toxicity of engineered nanomaterials (NPs).
- To explore NP exposure routes including skin, respiratory, and gastrointestinal tracts.
- To discuss the mechanisms of NP toxicity and their effects on mammalian organs.
Main Methods:
- Comprehensive literature review of nanotoxicity studies.
- Analysis of NP behavior and interaction with biological systems.
- Examination of toxicological data from various exposure pathways.
Main Results:
- Engineered NPs can cause cytotoxicity and genotoxicity in mammalian cells.
- The small size of NPs allows penetration into cells and disruption of normal function.
- Evidence suggests widespread harmful effects of NPs on various organs.
Conclusions:
- Thorough safety research, including environmental and health impact assessments, is essential.
- Open discussion on the societal implications of nanotechnology is required.
- Urgent toxicological oversight is needed to manage the risks associated with NP commercialization.

01:36Types 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.

01:26Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
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,...

01:24Microbial Corrosion
Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...
01:27The Periodic Table and Organismal Elements
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
