    Kuchenki gazowe zostaną zakazane? Oto co mówią fakty

    Paweł Usiądek na TikToku powiedział: "Kuchenki gazowe zostaną zakazane w Europie.
    Koniec z kuchenkami gazowymi. Kolejna zmiana, do której będziemy zmuszeni się
    dostosować. [...] Musimy przygotować się na nową erę, gdyż wszystkie kuchenki w
    domach na terenie Unii Europejskiej będą musiały zostać dostosowane do nowych
    standardów. W praktyce oznacza to, że będą musiały zostać wymienione"

    Kalifornia już zakazała gotowania na gazie.

    Ale prawdziwa przyczyna jest taka, że obecny gaz to gaz łupkowy, a gaz łupkowy
    podczas spalania, spala także trujący benzen, który zawiera, który jest rakotwórczy

    Gaz ziemny nie zawierał trującego benzenu, a gaz głupkowy zawiera

    Warning !!! Highly toxic and carcinogenic benzene in shale gas

    "Health effects
    A bottle of benzene. The warnings show benzene is a toxic and flammable liquid.

    Benzene is classified as a carcinogen, which increases the risk of cancer and other
    illnesses, and is also a notorious cause of bone marrow failure. Substantial
    quantities of epidemiologic, clinical, and laboratory data link benzene to aplastic
    anemia, acute leukemia, bone marrow abnormalities and cardiovascular
    disease.[73][74][75] The specific hematologic malignancies that benzene is associated
    with include: acute myeloid leukemia (AML), aplastic anemia, myelodysplastic syndrome
    (MDS), acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML).[76]

    The American Petroleum Institute (API) stated as early as 1948 that "it is generally
    considered that the only absolutely safe concentration for benzene is zero".[77]
    There is no safe exposure level; even tiny amounts can cause harm.[78] The US
    Department of Health and Human Services (DHHS) classifies benzene as a human
    carcinogen. Long-term exposure to excessive levels of benzene in the air causes
    leukemia, a potentially fatal cancer of the blood-forming organs. In particular,
    acute myeloid leukemia or acute nonlymphocytic leukemia (AML & ANLL) is caused by
    benzene.[79] IARC rated benzene as "known to be carcinogenic to humans" (Group 1).

    As benzene is ubiquitous in gasoline and hydrocarbon fuels that are in use
    everywhere, human exposure to benzene is a global health problem. Benzene targets the
    liver, kidney, lung, heart and brain and can cause DNA strand breaks and chromosomal
    damage, hence is teratogenic and mutagenic. Benzene causes cancer in animals
    including humans. Benzene has been shown to cause cancer in both sexes of multiple
    species of laboratory animals exposed via various routes.[80][81]
    Exposure to benzene

    According to the Agency for Toxic Substances and Disease Registry (ATSDR) (2007),
    benzene is both a synthetically-made and naturally occurring chemical from processes
    that include: volcanic eruptions, wild fires, synthesis of chemicals such as phenol,
    production of synthetic fibers, and fabrication of rubbers, lubricants, pesticides,
    medications, and dyes. The major sources of benzene exposure are tobacco smoke,
    automobile service stations, exhaust from motor vehicles, and industrial emissions;
    however, ingestion and dermal absorption of benzene can also occur through contact
    with contaminated water. Benzene is hepatically metabolized and excreted in the
    urine. Measurement of air and water levels of benzene is accomplished through
    collection via activated charcoal tubes, which are then analyzed with a gas
    chromatograph. The measurement of benzene in humans can be accomplished via urine,
    blood, and breath tests; however, all of these have their limitations because benzene
    is rapidly metabolized in the human body.[82]

    Exposure to benzene may lead progressively to aplastic anemia, leukaemia, and
    multiple myeloma.[83]

    OSHA regulates levels of benzene in the workplace.[84] The maximum allowable amount
    of benzene in workroom air during an 8-hour workday, 40-hour workweek is 1 ppm. As
    benzene can cause cancer, NIOSH recommends that all workers wear special breathing
    equipment when they are likely to be exposed to benzene at levels exceeding the
    recommended (8-hour) exposure limit of 0.1 ppm.[85]
    Benzene exposure limits

    The United States Environmental Protection Agency has set a maximum contaminant level
    for benzene in drinking water at 0.0005 mg/L (5 ppb), as promulgated via the U.S.
    National Primary Drinking Water Regulations.[86] This regulation is based on
    preventing benzene leukemogenesis. The maximum contaminant level goal (MCLG), a
    nonenforceable health goal that would allow an adequate margin of safety for the
    prevention of adverse effects, is zero benzene concentration in drinking water. The
    EPA requires that spills or accidental releases into the environment of 10 pounds
    (4.5 kg) or more of benzene be reported.

    The U.S. Occupational Safety and Health Administration (OSHA) has set a permissible
    exposure limit of 1 part of benzene per million parts of air (1 ppm) in the workplace
    during an 8-hour workday, 40-hour workweek. The short term exposure limit for
    airborne benzene is 5 ppm for 15 minutes.[87] These legal limits were based on
    studies demonstrating compelling evidence of health risk to workers exposed to
    benzene. The risk from exposure to 1 ppm for a working lifetime has been estimated as
    5 excess leukemia deaths per 1,000 employees exposed. (This estimate assumes no
    threshold for benzene's carcinogenic effects.) OSHA has also established an action
    level of 0.5 ppm to encourage even lower exposures in the workplace.[88]

    The U.S. National Institute for Occupational Safety and Health (NIOSH) revised the
    Immediately Dangerous to Life and Health (IDLH) concentration for benzene to 500 ppm.
    The current NIOSH definition for an IDLH condition, as given in the NIOSH Respirator
    Selection Logic, is one that poses a threat of exposure to airborne contaminants when
    that exposure is likely to cause death or immediate or delayed permanent adverse
    health effects or prevent escape from such an environment.[89] The purpose of
    establishing an IDLH value is (1) to ensure that the worker can escape from a given
    contaminated environment in the event of failure of the respiratory protection
    equipment and (2) is considered a maximum level above which only a highly reliable
    breathing apparatus providing maximum worker protection is permitted.[89][90] In
    September 1995, NIOSH issued a new policy for developing recommended exposure limits
    (RELs) for substances, including carcinogens. As benzene can cause cancer, NIOSH
    recommends that all workers wear special breathing equipment when they are likely to
    be exposed to benzene at levels exceeding the REL (10-hour) of 0.1 ppm.[91] The NIOSH
    short-term exposure limit (STEL - 15 min) is 1 ppm.

    American Conference of Governmental Industrial Hygienists (ACGIH) adopted Threshold
    Limit Values (TLVs) for benzene at 0.5 ppm TWA and 2.5 ppm STEL.[citation needed]
    Toxicology
    Biomarkers of exposure

    Several tests can determine exposure to benzene. Benzene itself can be measured in
    breath, blood or urine, but such testing is usually limited to the first 24 hours
    post-exposure due to the relatively rapid removal of the chemical by exhalation or
    biotransformation. Most people in developed countries have measureable baseline
    levels of benzene and other aromatic petroleum hydrocarbons in their blood. In the
    body, benzene is enzymatically converted to a series of oxidation products including
    muconic acid, phenylmercapturic acid, phenol, catechol, hydroquinone and
    1,2,4-trihydroxybenzene. Most of these metabolites have some value as biomarkers of
    human exposure, since they accumulate in the urine in proportion to the extent and
    duration of exposure, and they may still be present for some days after exposure has
    ceased. The current ACGIH biological exposure limits for occupational exposure are
    500 ?g/g creatinine for muconic acid and 25 ?g/g creatinine for phenylmercapturic
    acid in an end-of-shift urine specimen.[92][93][94][95]
