How to Protect Yourself From Saharan Dust
Such events occur in the Caribbean and the Gulf Coast region several times a year, and scientists are studying how climate change may affect their frequency and intensity.
Here is what research shows about the health effects of Saharan dust exposure, and how people can protect themselves.
What is in the dust plume?
Dust plumes like this one originate in deserts, in this case, the Sahara. The dust is composed mainly of minerals found in desert sand, including silicates such as quartz.
But as they travel, plumes can pick up other pollutants, as well as bacteria, viruses and fungi. Reactions among the pollutants, and between those pollutants and sunlight, can produce additional chemicals as well.
What are the effects of exposure?
What makes Saharan dust dangerous is that its particles are extremely small, which means they can be inhaled deep into the lungs, irritating and damaging them.

Toxic algae is threatening a pond on Martha's Vineyard. A new tool could change that.
A beloved pond on Martha's Vineyard is being choked by toxic algae, but a new piece of technology could help save it. Every year tens of thousands of people flock to Martha's Vineyard for the sun, the sand and the scenery. But in order to keep this special sanctuary safe, unique solutions are needed to fight our changing climate. High above the southern part of the Massachusetts island, the Atlantic Ocean collides with the shore. Just beyond that sits 200 acres of brackish water that makes up Chilmark Pond. It looks inviting, but a danger lurks in these waters. Over the last several years, toxic blooms of cyanobacteria have taken over. Arnie Spevack and Sharon Siegel live on Chilmark Pond. They remember a time when the pond was a place for play, a passageway to the beach, and the wonders of summer. "Martha's Vineyard generally is just paradise," Arnie Speevak said. "My grandchildren used to swim in this pond. And they can't anymore," added Sharon Seagull. Cyanobacteria, sometimes called blue-green algae, are microscopic organisms that thrive in warm, nutrient-rich water. They feed on nitrogen and phosphorus. In summer, they can multiply fast enough to choke a pond and produce toxins that can make people and pets sick. "This pond is really delicate," Emily Reddington said. Reddington leads the Great Pond Foundation. She said the challenge was finding a fix that wouldn't hurt the ecosystem they're trying to save. They turned to the LG Sonic MPC-Buoy, a solar-powered piece of technology that they hope can save Chilmark Pond. "Instead of adding a chemical or disturbing the environment, it uses sonic pulses targeting specifically cyanobacteria to keep from growing out of control or blooming," Reddington said. Every 30 minutes, the device checks the water's vital signs and sends out sound waves that block algae from the sunlight it needs to grow. Without it, the blooms can surface, spread and release dangerous toxins. The buoy is treating the symptoms — the blooms you can see. But to find the source of the problem, you have to look beneath the surface, into the soil and aging septic systems around the pond. The issue is not specific to Chilmark Pond, Martha's Vineyard, or even Massachusetts. It's a worldwide issue. "100 percent, this is a global challenge that we're having to deal with across the world. Temperatures are increasing, precipitation is changing, and pressures on the environment are increasing over time," Reddington said. At any given time, dozens of cities and towns in Massachusetts have closed beaches because of cyanobacteria. And it's not just small bodies of water, for example, these algae blooms are also a common occurrence in three of the Great Lakes - Erie, Michigan, and Superior. That's why Reddington's team heads out daily to gather water for testing. "The more data the better," Reddington said. Once the water's back at the Vineyard Haven Lab, it's analyzed sample by sample. "This machine is telling us specifically what phytoplankton or what combination of phytoplankton is growing and giving the water that hue," Owen Porterfield said. "What we are registering is a moderate to high concentration of cyanobacteria." All this data goes straight to the Board of Health, the people who make the call on public safety "The signs were ready to go. The maps went up the same day, and we kind of have a weekly workflow, but if it's a bloom, those are posted the same day," Reddington said. Back on the pond, those who live along the water like the president of Chilmark Pond Association Amy Salzman, say the new sonic buoy is bringing a new sense of hope. "If it works, it could be a game changer for the island, for the Cape," Salzman said. She believes people and nature share a symbiotic relationship and losing something like the pond to climate change would be unimaginable. "We've gotten so enclosed in our urban world and one of the most important things we can do for nature is to get people out in it," Salzman said. "And restoring this pond is such an opportunity to reconnect people to it."

2 hospitalized, 17 treated after possible chemical spill in Doral, authorities say
Two people had to be rushed to a local hospital and seventeen others were treated on scene following a possible chemical spill in Doral Tuesday afternoon, according to Miami-Dade Fire Rescue. It happened in the area of NW 19th Street and 102nd Avenue. The two people hospitalized were taken to Jackson Memorial Hospital. In a statement, Miami-Dade Fire Rescue said units first responded to a medical call "possibly related to an electrocution." Crews used a basket to lower one adult trauma-alert patient, who was transported by ground to a trauma center. Minutes later, the department said the call was updated to a hazardous situation involving a possible chemical spill. Firefighters began triage for patients inside the structure and worked to locate and mitigate the source of the leak. Due to the number of people affected, the incident was upgraded to a Level 2 mass casualty event. Miami-Dade Fire Rescue said 17 patients were ultimately treated, all with non-life-threatening injuries.

Miami woman warns pet owners after dog contracts deadly parvovirus
A Miami woman is urging dog owners to take precautions after her 14-year-old pet was diagnosed with parvovirus, a highly contagious and sometimes fatal illness that veterinarians say can spread quickly in apartment complexes. "I mean I look into her eyes and it's so hard because I know what's coming and she doesn't…um, it's very sad and it's preventable," said Gilat Schwartz, owner of Bella, the dog diagnosed with the virus. For 14 years, Bella was a lively, happy companion. But on Sunday night, Schwartz noticed something was wrong when she saw blood in Bella's stool. Soon after, Bella began vomiting and showed signs of low energy—symptoms veterinarians say are common with parvovirus. By Monday afternoon, Bella was placed in hospice care. Schwartz believes her dog contracted the virus in their apartment complex's dog area. "There's people not picking up after their pets and they should take that seriously. We know that our pets don't last as long as we do, but this way of her dying is just so unfair and unnecessary, and it could've been prevented," Schwartz said. Dr. Jen Garner, a veterinarian with Chewy Vet Care, said the illness spreads easily in areas where many dogs share outdoor space. "It is spread through the stool, sometimes also through vomit, but since it is so highly contagious, it does not take a lot of virus particles to infect the dog that is susceptible," Dr. Garner said. "So when they go in and just walk across an area that has been contaminated, even if the poop has been removed, and they lick their paw, that can actually transmit the virus." Dr. Garner said parvovirus attacks a dog's intestinal tract and can survive in soil or grass. "The virus, if not treated, is up to 90% fatal. With treatment, it can have a 90% cure rate," she said. Veterinarians say prevention is the most effective protection against parvovirus. "Simply because Parvo is not the only thing they can get. They can also pick up an intestinal parasite, other bacterial diseases, and overall it's just not a sanitary condition," Dr. Garner said. Experts advise keeping vaccines up to date, picking up after pets and avoiding areas where stool is present. For Schwartz, sharing Bella's story is about warning others. She said she hopes pet owners will take the virus seriously and protect their dogs from unnecessary suffering.
